For myself, I entered into life with one goal: to learn what emotions are. For myself, there was no other reason for being here.
I continuously observed and analyzed everything I saw, smelled, tasted, heard, and felt. As an adult I started my own business doing the same as an electronics tech. I studied religions, philosophies, sciences, and most everything else available in books, but still I found nothing about emotions. Everyone I met exhibited similar emotions as other people, but I still felt that I had not experienced what I wanted to find. For myself, I cared about people, but I had no strong emotions, nor had I learned what the emotions of envy, greed, and hate were. To most people I likely appeared to be overly reserved and quiet, with logic being my only guide.
Within my hobby of writing non-fiction books and articles, for fun I began writing a book of fiction. The book was to only have positive events and positive people (things that cannot occur in the world today); just something nice to think about. After seeing how the first book-length chapter enhanced positive emotions (my wife frequently strongly cried with happiness for another person's happiness while reading it (I did also)), I then designed the following books to purposefully further enhance positive emotions (there are currently 16 book-length chapters in the book, about 1.3-million edited words).
As the different stories developed, I recognized specific sequences that heighten emotions, of which when used, enabled me to wail with happiness and love for another person's happiness (my shirtsleeves always remained wet from wiping my tears while working on the stories).
One story is so strongly emotional, for over five years I could not so much as begin to speak the title name without my first breaking down in tears of love and heartache for a beautiful person. I still have to struggle to speak of the story. Merely hearing the first few seconds of the background music had the same effect, and still does. (My eyes are watered as I write this.)
Another story was so strong... seriously, it was too strong. I had to quickly add an after-event that enabled the story ending to soothe the too-intense emotions.
I had finally found what love is. To me, love is the ultimate spirituality, to love another soul so utterly strong and deeply, that one's own life, heart, and soul are unhesitatingly given with love.
Finally, after so many years, I finally found what I came in search of. Finally, my life now has meaning.
